A fuel coil 2S is disposed concentric With the diffusion tube 6 and isin communication with a fuel supply tube 29 at one end thereof and incommunication With the diffusion tube at the other end thereof indicatedat 30. rEhe fuel supply tube extends through the cap 7 and is incommunication with a fuel supply pipe 31 by means of a valve 32. A Waterfeeding pipe 33 is disposed in communication With the fuel supply tube29 by means of avalve 34 so that a small quantity of water may be mixedWith the'fuel. The mixture of the Water and the fuel serves thefollowing purposes: Under the influence of heat such as hereinafterexplained, the fuel is volatilized and the Water becomes more or lesshighly heated steam. Under this condition the particles ofi-l2() andfuel vapor attain enormous velocities in different directions. rlCheseparticles come into collision With one another With great violence andthese collisions aid incracking or breaking up the fuel and also causethe vaporized Water and steam to diffuse one with the other. The Wateror steam in the diffusion tube tends to slightly retard combustion sothat when the fuel is ignited the force of the explosion is distributedover a longer periodof time Without appreciably diminishing the pressureWhich the combustion of the fuel provides for power purposesl It will bereadily understood by looking at Figure 2 that the average rate of flowof the fuel and Water in the diffusion part is much less than it isWhile the steam .and fuel are passing through parts 28, rEhe fuel andWater have therefore a relatively longer time to remain in the diffusiontube and mii; thoroughly therefore making a more efficient fuel mixture.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. With this type ofcombustion generator, various grades of fuel Vmay be used. With theinferior grades of fuel, a mixture of Water is necessary. However, withthe superior grades of fuel, the mixture of Water is not needed. XWiththe introduction of volatile fuel through the fuel tube 29 and out intothe fuel diffusion tube 6 through the coil 28, there is obtained acombustible mixture by the time it reaches the innermost end of thediffusion tube. kAs the combustible mixture passes around the annularguide portion 17 and through the opening 18, `it mines with the .air andis ignited by the spark plug 20.

YWith the increase of temperature in the casing, heavy fuels and iva-terare continuously introduced to the fuel tube 29 and combustion ismaintained spontaneously between the head portion 8 and the combustionblock 10, Where the fuel continues to come in contact With the airforced in through the air tube 14. 'lhe gaseous by-products, Which areexhausted through the irregular passageway 12, heat the coils 21 and 28.rllherefore, by introducing Water through the Water tube 22 and into thecoil 21, steam is produced, due to the heat in the casing. The steam isallowed to pass through the coil 21 and into the casing, Where it actsas an auxiliary means for maintaining the heat Within the casing forheating the Water entering the coil 2l. Furthermore, by this same meansthe mixture of fuel is preheated Within the coil 28 beforeit isallowedwto pass into the fuel di usion tube (i. The steam and theby-products pass through the outlet 2.7 at a rate of speed determined bythe pressure maintained in pipes 15, 2a', 31, and 33, and the relativelyopen or closed positions of valves 16, 25, 32, and 34. The valvev 25varies the speed at which the Water is allowed to pass through the Watertube 22 and into the coil 21.

The gases of combustion mingle with the `sain in the casing and. aid inheating the diffusion tube G, the coils 28 and their contents, and alsothe coils 21 and their contents. The steam', together with thecombustion gases, passes fr in the casing through the out-let 2'?.
